I have a basic system working with one client, seven dataservers, and a redirector. The client can store correctly but I am observing a consistent five second delay when the client is storing data. I ran xrdcp with -d 3 and the output contains : 071207 23:03:40 001 Xrd: DoLogin: No prev session info for 10.1.2.255:1094 071207 23:03:40 001 Xrd: Open: Access to server granted. 071207 23:03:40 001 Xrd: Open: Opening the remote file /xrd/test24/100mb 071207 23:03:40 001 Xrd: Open: File open in progress. 071207 23:03:40 18805 Xrd: XrdClientMessage::ReadRaw: Reading header (8 bytes). 071207 23:03:40 18805 Xrd: ReadRaw: Reading from 10.1.2.255:1094 071207 23:03:40 18805 Xrd: SendGenCommand: Sending command Open 071207 23:03:40 18805 Xrd: WriteRaw: Writing 24 bytes to physical connection 071207 23:03:40 18805 Xrd: WriteRaw: Writing to substreamid 0 071207 23:03:40 18805 Xrd: WriteRaw: Writing 17 bytes to physical connection 071207 23:03:40 18805 Xrd: WriteRaw: Writing to substreamid 0 071207 23:03:40 18805 Xrd: ReadPartialAnswer: Reading a XrdClientMessage from the server [10.1.2.255:1094]... 071207 23:03:40 18805 Xrd: XrdClientMessage::ReadRaw: sid: 1, IsAttn: 0, substreamid: 0 071207 23:03:40 18805 Xrd: XrdClientMessage::ReadRaw: Reading data (4 bytes) from substream 0 071207 23:03:40 18805 Xrd: ReadRaw: Reading from 10.1.2.255:1094 071207 23:03:40 18805 Xrd: BuildMessage: posting id 1 071207 23:03:40 18805 Xrd: XrdClientMessage::ReadRaw: Reading header (8 bytes). 071207 23:03:40 18805 Xrd: ReadRaw: Reading from 10.1.2.255:1094 071207 23:03:40 18805 Xrd: ReadPartialAnswer: Server [10.1.2.255:1094] answered [kXR_wait] (4005) 071207 23:03:40 18805 Xrd: CheckErrorStatus: Server [10.1.2.255:1094] requested 5 seconds of wait 071207 23:03:42 18805 Xrd: DumpPhyConn: Phyconn entry, [log in to unmask]:1094', LogCnt=1 Valid 071207 23:03:44 18805 Xrd: DumpPhyConn: Phyconn entry, [log in to unmask]:1094', LogCnt=1 Valid 071207 23:03:45 18805 Xrd: SendGenCommand: Sending command Open It appears that the client received a 5 second delay from the redirector. I don't seen any useful information in the olbd log of the redirector and the xrootd log only indicates that the client was asked to wait: 071207 22:54:24 15092 odc_send2Man: root.18805:16@compute-0-0 asked to wait 5 by xrdb path=/xrd/test24/100mb How do I determine why the redirector is sending xXR_wait? Is the result of my configuration defaulting to round robin scheduling? Thanks, Patrick
